This looks like a pretty cool device. The Black Dog is a small USB computer that is running Debian, that when authenticated with biometrics launches a X server on the host computer. Then you can interact with the computer in that way.
I would assume that this will only work if the host computer is set to to support USB networking. Also I assume that if this computer needs access to the network, the host computer will need to install firewall in bridging mode.
